[Resolved] Installation fails on 10.14.x

[Waldemar]

Dear Team,

I try to install VirtualBox 5.2.20 on a fresh Mac OS 10.14 and get during install follow message, please have a look in the attachment.

Thank you for help and answer.

There's a sticky, at the top of the "OSX Hosts" section: Installation fails on 10.13.x (rc=-1908). Follow the instructions and allow Oracle in the System Preferences » Security control panel.

Hello socratis,

thank you for coming back on this.
Attach you will find two files. The installation and dmesg file. Hope this will help.

Follow the instructions and allow Oracle in the System Preferences » Security control panel.
Done!

No, not really. I think you got the log before you allowed Oracle, then you didn't try to install in again. Please re-run the installer, after you've allowed Oracle in the System Preferences.

Hello socratis,

thank you for the fast response.

I uninstall virtualbox, reboot and install once again. Attach you will find the logs.
Hope that I do everything correct

You're supposed to allow Oracle in that dialog that you posted; press the "Erlauben" button. You didn't.

[Waldemar]

Hello socratis,

thank you for the feedback. The button "Erlauben" doesn't appear anymore. Can i do it manually?

[socratis]

If it doesn't appear there are two things that might be going on: 1) You already allowed Oracle, or 2) the timeout period of 20-30 minutes has passed.

1. Reboot the computer.
2. Install (or try to) VirtualBox. If it works (success), great. You're done.
3. If it fails with that error message, go to the Security options, allow Oracle.
4. Re-install VirtualBox.

Hello Socratis,

thank you for fast help.
I checked once again the Security options and know I saw that I have to allow Oracle.
Re-install works

Thank you very much for help.


All the best

Waldemar
